     getName= t_studentName.getText();
}

Answer 1

if this is in the constructor
getName= t_studentName.getText();
getname wil be whatever is in t_studentName at that time - probably ""
it is not like Excel's automatic recalculation.
try changing
nameArea.setText(getName);
to
nameArea.setText(t_studentName.getText());
